ListView在ScrollView中不显示全部的问题

    /**     * 通过设置它的高度，让它“放弃”自身滚动属性，而放置到ScrollView中使用的。     *      * @param lv     */    private void setListViewHeight(ListView lv) {        ListAdapter la = lv.getAdapter();        if (null == la) {            return;        }        // calculate height of all items.        int h = 0;        final int cnt = la.getCount();        for (int i = 0; i < cnt; i++) {            View item = la.getView(i, null, lv);            item.measure(0, 0);            h += item.getMeasuredHeight();        }        // reset ListView height        ViewGroup.LayoutParams lp = lv.getLayoutParams();        lp.height = h + (lv.getDividerHeight() * (cnt - 1));        lv.setLayoutParams(lp);    }
